Instagram is useful for a number of things, from keeping in touch with your friends to documenting your last vacation.

But there are also a number of people who have gained fame by way of the social media platform.

These 27 star Instagrammers made a name for themselves by posting their photos, and look damn good doing it.

Jonathan Nafarrete

Followers: 20,899

Nafarrete isn't the star of his Instagram photos, but when he does appear in one it's usually with someone kind of famous (like Annalynne McCord from "Nip/Tuck").

The digital ad professional has collaborated with brands like Audi USA, Nike, Sheraton, and T-Mobile for their own Instagram photo campaigns, but in his spare time runs the group Instagram LA, which organizes "Instawalks" and networking opportunities for brands and Instagram users.

Broderick Hunter

Followers: 22,405

The 6'2" Southern California native was on a fast track to becoming a professional basketball player or physical therapist when a photographer discovered him on Facebook. Shortly after, Hunter modeled for his first shoot and posted the photos on social media. The overwhelming response from friends convinced him to make the career change.

Cailli and Sam Beckerman

Followers: 121,617

Equally gorgeous, the identical twins behind the popular style blog Beckerman Blog get tons of Instagram likes not just on their selfies, but on shots of their Pomeranian pooches (who share their love of style).

The Beckermans, who hail from Toronto, also use Instagram as an opportunity to promote their clothing line, which they started out of a Manhattan apartment with their younger sister, Chloe.

Brian DiFeo

Followers: 124,373

The co-founder of Mobile Media Lab, DiFeo got Instagram just weeks after it launched publicly. After realizing that by offering to manage brands' Instagram accounts in exchange for cool perks, a new job was born.

The adventurous DiFeo has photographed Volvo's Ocean Race in Abu Dhabi, the U.S. Open for Armani Exchange and Evian campaigns, and Rangers' games in exotic locales.

Harry Hudson

Rather than withdraw and quietly battle his way through the disease, the 20-year-old decided to fight loud and proud on Instagram and Twitter, picking up more than 200,000 followers and supporters along the way. The hashtag #prayforharry even started trending worldwide.

Bex Finch

Followers: 195,485

Finch gained Instagram stardom with her hashtag #fromwhereistand, which allows users to chronicle their lives from the perspective of looking down on their shoes. The hashtag (and camera angle) is incredibly popular with Instagram users.

Eelco Roos

But the Hague-based IT specialist and amateur photographer, who reached more than 100,000 Instagram followers within just a couple of months of starting his account, is also a much sought-after branding expert — Johnny Walker even flew Roos to Iceland to take over the company's Instagram account at a press event.

Theron Humphrey

Followers: 403,121

This dog lover and professional photographer crossed the country with his best friend Maddie the coonhound to create his photo documentary called "Why We Rescue," a candid account of a rescued pet (and its rescuer) in every state.

Lumberjack-like (in an adorable way), Humphrey first put his Instagram account on the map with a funny photo series of Maddie standing on a number of unlikely objects.

Rachel Brathen

Followers: 534,856

The Swedish native discovered yoga on a trip to Costa Rica after graduating from school, and fell madly in love with the practice — so much so that she decided to study and teach it herself. She hosts retreats in the Caribbean where, in addition to traditional yoga, she teaches a unique form known as SUP Yoga (Stand-Up Paddleboard Yoga).

With more than half a million Instagram followers, she is one of the most followed instructors in the world, dazzling the web with her flexibility and balance.

Hayden Williams

Followers: 539,023

Williams is best known for his Disney "'Vogue' covers," styling the princesses as if they were "Vogue" fashion models, but the British fashion illustrator has recently branched out into drawing other models and celebrities.

Disney has always been Williams' inspiration; he actually taught himself to draw when he was younger by copying the Disney princesses he saw on screen.

Murad Osmann

Followers: 655,649

Osmann and his globe-trotting girlfriend Natalia Zakharova are one of Instagram's most viral couples. Osman, a civil engineer turned professional photographer, snaps pictures of his girlfriend taking his hand and leading him through some of the world's most iconic and recognizable landmarks.

Steph Goralnick

Followers: 658,088

Though she prefers to remain behind the lens of a camera most of the time, brands are knocking on her door left and right begging her to come work with them. She's already completed a project with Delta — a project which came with a ton of perks and free swag for her.

Emily Ratajkowski

Followers: 689,520

Before the Polish-Israeli beauty stripped down in Robin Thicke's music video for "Blurred Lines," Ratajkowski signed with Ford Models, traveled the world, participated in #tbt, and ate Carl's Jr. burgers in jaw-dropping TV commercials. She was generous enough to share these experiences with Instagram.

Since her birthday-suit appearance in the song of the summer, Ratajkowski has been cast as Ben Affleck's mistress in the upcoming thriller "Gone Girl."

Cole Rise

Followers: 800,423

The puppy-eyed travel photographer, who is based out of San Francisco, doesn't just take breathtaking travel photos for himself, he takes them by the requests of various tourism boards, like Australia's and Iceland's.

Massiel Arias

Followers: 902,380

Arias' Instagram followers are in awe of her muscular selfies and, when Instagram video came out, her gravity-defying feats of strength.

A personal trainer by profession, Arias wears apparel supplied by Nike, Under Armour, and New Balance (without payment), but uses Instagram more as a tool to document her method of coping with depression, not ad sales.

Liz Eswein

Followers: 1.1 million

The cute brunette usually hides behind her smartphone serving as New York City's unofficial Instagram photographer, but in doing so she's gathered fame and fans in a major way.

Eswein wasn't sure if she wanted to use her own name as her Instagram handle, so she snagged @NewYorkCity just after Instagram came out. Now with over 1 million followers, she's one of the most followed, non-celeb Instagrammers.

Aimee Song

Followers: 1.2 million

Song blogs about fashion and interior design on her website Song of Style. Her unconventional grunge-chic look is mostly attention-grabbing, although her most-liked media of 2013 was a close-up of her purple, scalloped bikini top.

Finn and Jack Harries

Finn's Followers: 1.4 million

Jacks's Followers: 1.3 million

Identical twins Finn and Jack Harries are the incredibly handsome and charming brothers behind the YouTube comedy channel, JacksGap, which boasts more than 3 million subscribers and 137 million video views.

Last fall, the pair drove the length of India in tiny rickshaws to raise money for the Teenage Cancer Trust, and documented their adventures on YouTube and Instagram. The project, dubbed "Rickshaw Run," was sponsored by Sony Entertainment and Skype.

Chiara Ferragni

Followers: 1.7 million

Scrolling through Ferragni's Instagram feed can be as tempting as window-shopping in SoHo. The Italian fashion-blogger-turned-shoe-designer flaunts her impeccable taste and blonde tresses on social media.

Bethany Noel Mota

Followers: 2.2 million

Mota racks up hundreds of thousands of likes on her beauty- and fashion-related Instagram photos.

The 19-year-old selfie queen, who started documenting her self-styled hair and make-up how-tos on YouTube at age 14, has walked the Jingle Ball red carpet, has been featured on HuffPost Live, and is now the new face of her own clothing collection at Aeropostale.
